Although being silent, observing austerities and penances, learning the Vedic literature, undergoing ritualistic ceremonies, living in a solitary place and performing japa and transcendental meditation are approved means of liberation, they are meant for nondevotees or for cheaters who want to live at the expense of others. A pure devotee, however, being freed from all such deceptive activities, is able to see the Lord face to face.
The atomic theory of the composition of the cosmic manifestation is not factual. The Lord is the cause of everything, and therefore He is the cause of this creation. One should therefore always engage in devotional service by offering respectful obeisances to the Lord, offering prayers, working for the Lord, worshiping the Lord in the temple, always remembering the Lord and always hearing about His transcendental activities.
